Regulates to 0.7V. 4 6 COMP Compensation (Output): Pin for external compensation. 5 7 AGND1 Analog Ground. 6 8 EN/UVLO Enable (Input): Logic low turns the IC off. When the voltage drops below the band gap reference voltage of the IC the device turns off. This accurate threshold allows the pin to be used as an accurate under voltage lockout. 7 9 VIN Supply Voltage (Input): 8V to 40V. 8 10 VDD 5V Internal Linear Regulator from VIN. When VIN is <8V, this regulator operates in drop-out mode. Connect external bypass capacitor. 9 11 LSD Low-Side Drive (Output): High-current driver output for external low-side MOSFET. 10 12 PGND Power Ground: High current return for ext. Low side driver. 11 13 SW Switch Node (Output): High current output driver return. 12 14 HSD High-Side Drive (Output): High current output-driver for ext. high-side MOSFET. 13 15 BST Boost (Output): Provides voltage for high-side MOSFET driver. The gate drive voltage is higher than the source voltage by VDD minus a diode drop. 14 16 CS Current Sense (Output): Current-limit comparator non inverting input. The current limit is sensed across the low- side FET during the OFF time. Current limit is set by the resistor in series with the CS pin. 15 1 AVDD Analog Supply Voltage (internal 5V LDO): Connect external By pass capacitor. 16 2 PGOOD Power Good (Output): High output when VOUT > 90% nominal.

MIC2130/1 Pin Description Pin Number Pin Number Pin Name Pin Function MLF-16 e-TSSOP-16 1 3 HCL* High Current Limit (Output): The capacitor on this pin sets AGND2 the duration of time so that the current limit will be set to 200% of its nominal set current. AGND2 for MIC2130 2 4 SS Soft Start (Output): Active at Power-up, Enable, and Current Limit recovery. 3 5 FB Feedback (Output): Input to error amplifier. Regulates to 0.7V. 4 6 COMP Compensation (Output): Pin for external compensation. 5 7 AGND1 Analog Ground. 6 8 EN/UVLO Enable (Input): Logic low turns the IC off. When the voltage drops below the band gap reference voltage of the IC the device turns off. This accurate threshold allows the pin to be used as an accurate under voltage lockout. 7 9 VIN Supply Voltage (Input): 8V to 40V. 8 10 VDD 5V Internal Linear Regulator from VIN. When VIN is <8V, this regulator operates in drop-out mode. Connect external bypass capacitor. 9 11 LSD Low-Side Drive (Output): High-current driver output for external low-side MOSFET. 10 12 PGND Power Ground: High current return for ext. Low side driver. 11 13 SW Switch Node (Output): High current output driver return. 12 14 HSD High-Side Drive (Output): High current output-driver for ext. high-side MOSFET. 13 15 BST Boost (Output): Provides voltage for high-side MOSFET driver. The gate drive voltage is higher than the source voltage by VDD minus a diode drop. 14 16 CS Current Sense (Output): Current-limit comparator non inverting input. The current limit is sensed across the low- side FET during the OFF time. Current limit is set by the resistor in series with the CS pin. 15 1 AVDD Analog Supply Voltage (internal 5V LDO): Connect external By pass capacitor. 16 2 PGOOD Power Good (Output): High output when VOUT > 90% nominal.
